syntheses of L-carbocyclic 2',3'-didehydro-2',3'-dideoxy- and 2',3'-dideoxypyrimidine and purine nucleoside analogues were accomplished, and their anti-HIV and anti-HBV activities were evaluated. The key intermediate, (1S, 4R)-1-benzoyloxy-4-(tert-butoxymethyl)cyclopent-2-ene (7), was prepared by benzoylation of the alcohol 2, selective deprotection of the isopropylidene group of 3, followed by thermal elimination
